Discovery of rare breast cancer genes changes the prevention landscape in Saudi Arabia

In a remarkable scientific development representing a qualitative leap in healthcare in the Kingdom of Saudi Arabia, recent genetic studies have revealed rare genetic mutations linked to breast cancer, paving the way for a new era of precision medicine. This discovery is not merely a research achievement, but a cornerstone for building advanced national strategies for early detection, relying entirely on the genetic characteristics of each region's population, thus transcending traditional methods of diagnosis and treatment.

General context and importance of precision medicine

Breast cancer is one of the most common cancers among women globally and locally. Previous treatment protocols have relied on general criteria that may not be suitable for each patient's genetic makeup. This shift towards precision medicine enhances the chances of recovery by designing tailored preventive and treatment programs, thus reducing waste in healthcare resources and improving treatment outcomes. This aligns with the goals of transforming the healthcare sector in the Kingdom.

The unique characteristics of geographical regions: Asir as a case study

Dr. Fatima Asiri, a genetics specialist, confirmed that relying solely on testing for common and globally recognized genes is no longer sufficient to explain all cases of hereditary cancer in the Kingdom, given the significant genetic diversity across regions. She specifically pointed to the Asir region, where studies have revealed rare genetic mutations specific to its population, necessitating an update to routine testing lists to include these newly identified genes, thus ensuring accurate diagnosis.

Next-generation technologies (NGS) and the data revolution

Dr. Asiri explained that Next-Generation Sequencing (NGS) has revolutionized molecular diagnostics. This technology allows for the examination of thousands of genes in record time, with exceptional accuracy, and at a lower cost compared to traditional methods. This technological advancement empowers physicians to predict the future course of a disease and precisely identify risk factors, thus facilitating proactive preventative measures before the disease worsens.

Challenges and proposed solutions

Despite these promising prospects, Asiri pointed to a number of challenges facing the widespread adoption of these tests, most notably low public awareness and concerns regarding the privacy of genetic data. To overcome these obstacles, she emphasized the importance of:

• Establishing specialized national centers and biological sample banks to discover disease-causing genes locally.
• Developing human resources specialized in genetic counseling and interpreting the results of complex tests.
• Enact strict legal legislation to protect the genetic characteristics of individuals and prevent genetic discrimination.

She concluded by emphasizing that localizing genetic research and converting its outputs into clinical practices within hospitals is the only guarantee for the sustainability of healthcare development, and for providing medical care that is worthy of the citizen and based on his unique genetic fingerprint.
